问题 Can anyone tell me how to use the UIImagePickerController (camera and album) delegates determine the image's orientation, rotate accordingly, and assign it to a UIImageView? 回答1: No, UIImagePickerController cannot do it explicitly. If you want to determine based on image's content. It is kind of hard problem. How can you determine an image's orientation without understanding the content inside of it?

问题 I am facing a problem where-in I cannot select videos from the photo album in iPhone 2G/3G device. The default photos application does show videos and is capable of playing them, which in turn means that UIImagePickerController should clearly be capable of showing videos in photo album and selecting them. I have coded this to determine whether the device is capable of snapping a photo, recording video, selecting photos and selecting videos: // Check if camera and video recording are available
